No matter of how many you are losing, it never hurts any less because every bond and every relationship is unique although some other recurring part of the grieving/euthanazing process will get a bit easier because you can spot them and have worked through some decisions. If you struggle, you will find that our grieving guide contains some helpful practical tips.
It has been a horrible year indeed; especially as the deaths have come in bunches and not nicely spaced out. Even with guinea pigs going back half a century to my childhood and having had over 80 in my life by now, losing them still hurts.
After your experiences with your operated boy, would you really want to risk neutering and not just see whether you can find a little boyfriend instead? Look for one that is healthy but not dominant and sex beforehand (we will help you with that to make sure that there are no accidents). We also have bonding guides if needed.
While neutering has become a much safer procedure with the best of vets, it can come with a high risk of complications and even fatality with vets that are not familiar with guinea pigs.
